Explanation

To isolate DNA from a plant cell, the following steps and techniques are typically used:

### Step-by-Step Solution:

1. **Cell Wall Breakdown**:
- The first step in isolating DNA from plant cells is to break down the cell wall. Plant cells have rigid cell walls primarily composed of cellulose, which makes it challenging to access the DNA located in the nucleus.
- **Hint**: Remember that plant cells have a tough outer layer that needs to be broken down to access the DNA.
